Transformer substation - Import export

The compact transformer substations provide connections between industrial or residential consumers and the medium voltage network. Electroalfa produces prefab transformation stations of the MT/JT type Alfa Power, in a varied range of types and sizes, in standard production, but also derived products, adapted to the required application.To meet the market’s demands we design compact transformer prefabricated substations with concrete or metal enclosures with standard ranges from 160kVA to 1600 kVA (upon request, up to 2500KVA) with indoor or outdoor access.

Substations are transformer or distribution centers made of sheet steel in desired dimensions. They are suitable for use of all types of MV switchgears and LV panels. They are manufactured in the requirement number of sections and doors according to the project design. Strong construction made of sheet steel and profiles is painted with electrostatic powder paint or liquid paint for high corrosion resistance. In order to prevent the strong solar radiation in hot summer, the shell can be equipped with heat insulation material with low thermal conductivity, the most used fillers are: rock wool board, polystyrene foam, etc. Modular design in requested depth, width and length, in average 4 times lighter than a concrete version along with easy transport and commissioning are just some of the advantages of this solution. Compact substations are suitable for residential quarters, urban public utilities, renewable power plants, power distribution etc

Overhead and underground conductors in various designs and constructions for the construction of new lines, the repair of existing transmission grids, the connection of transformer substations, solar and wind power plants. Furthermore, the upgrading of existing lines with high-temperature conductors to increase transmission capacity.

The 400/230 Vac and 48…220Vdc auxiliary services cabinets are designated to supply the low voltage consumers within the 110/20(6)kV transformer substations of the power supply and distribution companies: Electrica SA, CEZ Group, ENEL Group, E.ON Group; Transelectrica’s 400/220/110kV connection and transformer substations; hydro power plants; thermal power plants.
